Question

Differentiate between the Following:

Ovulatory and Menstrual phase

Answer 1

Sr. No.	Ovulatory phase	Menstrual phase
1.	The ovulatory phase involves the release of a mature secondary oocyte from an ovarian follicle.	The menstrual phase involves the shedding of the uterine endometrium and the flow of blood.
2.	It usually occurs around the 13th–14th day of a 28-day cycle.	It begins on the first day of the cycle and usually lasts about 3–5 days.
3.	The released oocyte enters the fallopian tube and moves towards the uterus.	The endometrial lining breaks down when fertilisation has not occurred.
4.	It makes an egg available for possible fertilisation.	It marks the start of a new menstrual cycle as the ovary begins preparing another follicle.
